Blank screen of death! Why?

[slizardo]

I'm getting random (apparently) blank screens on my application
http://www.votelook.com (http://votelook.appspot.com)
I reviewed my code but I couldn't find any mistake related to this
issue. Have anyone of you encountered similar problems?

Thank you!

Hi,
 This can happen if you forget:

if __name__ == '__main__':
  main()

In your file.

-Marzia

You were right, I accidentally removed that sentences from my
application entry point.

Now it's solved, thank you!

Should i ask how that works?

The first load of the script does nothing, but is kept in ram because
it contains a main(), and it works from the second call onwards?

Is this an answer to your question ? http://docs.python.org/lib/module-main.html

I am not sure I understood it.

My guess is based on my understanding of appcaching:
http://code.google.com/appengine/docs/python/appcaching.html

Basically, if a script has a no argument main() function, it will get
cached, akin to FastCGI. The lack of a if __name__ == "__main__" test
would mean that on the *first* invocation, no output would be
produced, but there after it would work properly. I think.
